DUST-ARRESTER.

SPECIFICATION forming part of vLetters Patent No. 778,075, dated December 2.0, 1904.

To all whom it may concern: Be it known that I, GEORGE A. SAGER, a citizen of the United States, anda resident of Alfull, clear, and exact description.

The purpose of the invention is to provide adevice adapted to extract dust and foreign particles from the air to be fedto pneumatically-operated toolsl and devices, so that the air upon reaching .the operative parts of 'such tools or devices will be pure, and consequently said operative parts of the tools or devices will not become clogged byv foreign matter, as now frequentlyfhappens to such an extent as to render the tools or devices inoperative, necessitating time and expensein cleaning.

- The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of one form of the device adapted particularly to be l ticularly'for locomotive use in connection with' the air-pumps ofair-bralre systems, and Fig. 5 is a sectional plan view of the device as illustratedin Fig. 4 and partly broken away.

In the form of the deviceshown in Figs. 1, 2, and 3, A represents the body of the device, which is shown circular in form, although it may have any desired shape. The said body A is shown provided with an outwardly-extending upper lange 10, and the said body is provided with a bottom 11, at the central-portion of which'bottom a pipe 12 vis either se- Application filed July 21, 1904. Serial No. 217,575.

curedor is integrally produced, said pipe 12 being open at the top and at the bottom. f The pipe12 is provided at its upper end with 'a downwardly-extending and outwardly-flaring ange 13. This pipe 12 extends within the body A to a pointnear'its top and is provided usually at its lower end below the bottom 11 with a'flange 12b, so lthat the pipe 12 may be y readily connected with another pipe or a system of pipes leading to the air-compressing machine employed. The body Ais coveredat the top by a partition or diaphragm 12, which partition or diaphragm extends out usually'to the outer edges of the flange 10 of the body. This partition or diaphragm 12a is provided with any desired number of tubes l13, secured in said partition or diaphragm 12EL at their upper ends in any'approved manner, the said tubes 13 being carried through the said partition or diaphragm, and the tubes 13 extend downward to Within a predetermined distance of the bottom 11 ofthe body A, as is shown in Fig. 1, forming in the said body A below the said tubes a chamber 14, adapted to contain oil, water, or any liquid capable of' attracting and retaining such foreign material as generally accompanies air from the outside atmosphere. The bottom 11 is provided with an outlet 15 in communication with the liquidreceiving compartment or chamber 14C, and this outlet 15 may be connected with a pipe leading wherever desirable. This pipe may also be provided with avalve, so that the liquid inthe body A may be drawn off at any f time. A top section or cover B is provided for the said body A, and this top section B is preferably of conical formation, as is shown in Fig. 1. A circular vertical section B is carried up from the upper portion of thevsaid top section, and a hood or cap 16 is supported a desired distance above the top of the extension B of the top section by means of straps 17 or their equivalents, the incoming air to the top section or .cover B passing beneath said hood or cap'. The'top section or cover B and the diaphragm or partition 12a may be secured to the body A in any desired manner. Usually, however, they are connected by means of bolts 18, having suitable nuts 19 applied, asis illustrated in Fig. 3. The oil or TOO liquid employed may be introduced into the liquid-receiving section 14 of the body A in any desired way. Usually, however, the liquid is introduced through a tube 2f), located in the top section B, normally closed by a plug 21, as shown. In the operation of this form of the device the air laden with impurities enters the device between the cap 16 and the opposing portion of the extension B of the top section and passes down into the top section, from thence through the tubes 13, where the air is made to impinge on the liquid in the chamber-section 14 of the body, as is indicated by the arrows in Fig. 1, and at such times the foreign particles brought into the device by the air will be attracted and held by the liquid at the bottom of the said body A.. The air thus purified, as is indicated by the arrows in Fig. 1. ascends around the central pipe 12 and is drawn down through said pipe 12 by the action of the air-compressing device employed. Thus it will be observed that the air which is supplied to the air-compressor and from the air-compressor to a pneumatically operated tool is practically free from all foreign matter and there is no tendency to clog the operative parts of the tool, as frequently happens when the air is drawn direct from the outside atmosphere and is so conveyed to the compressor and tool.

In Figs. 4 and 5 I have illustrated a form of device adapted to be used particularly on locomotives in connection with the air-pumps of air-brake systems to prevent foreign matter entering the systems. In this form of the device the body C is shown as circular, although it may be of other form, and is open at the top and bottom; but at the bottom portion of the body C a tank C is removably secured by means of screws 22 0r their equivalents, the bottom of the tank Cf forming the bottom of the body C. The bottom part of the tank, although itis shown removable from the sides thereof, can be integral with the sides, if desired; but the bottom portion of the tank should extend down far enough below the bottom proper to receive the screws 22 or other fastening devices employed. A top section or cover D is provided for the body C, and this top section or cover is preferably provided with a downwardly-extending marginal flange 23, having' a groove therein to receive the upper edge of the body U, and this cover D may be secured to the body C by passing' screws, rivets, or the like through the flange 23 and through openings 24 in the body, as shown in Fig. 4. The top section or cover D is provided with a series of tubes 25, suitably secured therein, the said tubes eX- tending entirely through the said cover and down to a point within the tank C above the level of the liquideoil, water, or the like-contained in the said tank, as is also shown in Fig. 4. The top section or cover D is provided with a central opening around which the bottom located at the upper portion of the neck 25",

the air to be purified or filtered, as it were, being" made to pass between the said hood -and the cover I), entering and passing down through the tubes 25, as is indicated by the arrows in Fig. 4, whereupon the air is forced to impinge upon the liquid in the tank C and then passes up in its purified form through the coupling 26 and the neck 25. The air may strike the liquid so forcibly as to cause the same to be unduly agitated, and in order te prevent the liquid from passing up under such conditions to the tubes 25 an overfiow-pipe 28 is secured in the bottom of the tank C', extending to any desired point. This overfiow-pipe 28 is provided with a cap 2f), held spaced from its upper end by suitable straps 30. Then the tank requires cleaning, it is simply necessary to remove the devices employed to fasten it to the body C, whereupon the tank may be drawn out from the body, cleaned, and readily replaced.

It will be noted that in each of the embodiments of my improvements herein shown the outlet for the purified air is located entirely within the boundaries or horizontal dimensions of the body and the top section of the structure, so that the use or employment of an outer casingis entirely dispensed with and the structure reduced to compact fo rm. I also dispense with the use of outer pipes or other appurtenances at the sides of the structure, which would bc an obstruction in the intended applications of the structure, and l have found that increased results are obtained by locating the ai-r-outlet centrally of both the body and top section thereof, since the currents of purified air tend to fiow in that direction, due to the fact that there are no side outlets therefor. IVith the embodiment shown in Fig. 4 it has also been found rulvantageous to locate the overflow-pipe 2S centrally of the body, since the same is thereby rendered equally available irrespective of the side or direction from which any undue agitation of the liquid in the body may proceed.

Having thus described my invention, l claim as new and' desire to secure by Letters Patent- 1. A dust-arresting device, comprising a body adapted to contain a liquid, a top section detachably seated upon the body, the joint between the two being closed, said top section being formed with a central vertical extension, a hood supported by the extension, for deflecting air downwardly within the device, tubes pendent from the top section, for directing the incoming air to and against the surface of the IOO liquid, and an outlet for the puriied air eentrally disposed with relation to both the body and top section and the tubes.

surface of the liquid, an outlet for the purified Y air, eentijally disposed with `relation to botli the body and top section and the tubes, and a 15 Centrally-disposed liquid-overflow pipe eX- tending upwardly within the body.

In testimony whereof I have signed my name p to this specification in the presence of two subscribing witnesses.

GEORGE A. SAGER.
